Title: Transmission system
IPC: H04Q1/453
Filed: 1969-04-08
Abstract: 1,268,782. Voice immunity receivers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 8 April, 1969 [10 April, 1968], No. 17896/69. Heading H4R. Voice frequency signal receiver in a system in which signalling frequencies are transmitted at a level lower than speech signals, and in which signals other than the signalling frequency inhibit the operation of a relay stage responsive to the signalling frequency, includes a limiting amplifier stage preceding the frequency selective stage, which clips the input signal at a level just above the nominal signalling level and below nominal speech signal level. As described, a bridge circuit comprising the secondaries of transformer 4, resistor 6 and circuit 5, resonant at the signalling frequency, is balanced at the signalling frequency but produces an output at all other frequencies, which output makes transistor 8 conduct and reduces the possible signal output of transistor 9, which is fed with the signalling frequency derived from the tuned circuit 5. Presence of signalling frequencies without interfering frequencies cause transistor 13 of the switching circuit 12 to conduct, turning off transistor 14 and releasing the signalling relay 16. Additional speech immunity is provided by the limiting amplifier stage, 2, comprising transistor 19 which is driven between cut-off and saturation by speech signals or other interfering signals above the nominal level of the signalling signals, which just do not overload the amplifier.

A " self-cancelling " arrangement to prevent the door being locked inadvertently when members 17, 22, 25 are in the locked position is arranged so that on slamming the door initial rotation of the latch cam 2 on engagement with the keeper, causes the limb 30 of the sill control link 22 to be engaged by a peg 33 of arm 8 so that the link 25 is moved into the position in Fig. 3 through sympathetic movement of lever 17. " Keyless " locking is effected by moving the sill control 22 to the locked position, and depressing the push-button before closure of the door to move the pin 27 along the slot 29b so that the link 25 is restrained against return to the normal position. The internal release mechanism comprises a pivoted bell-crank lever 32 bearing an arm 40 which engages the pin 33 of the arm 8. A keeper for the latch, Fig. 2 (not shown), comprises an upper guide member which engages in the closed position a yoke 47 of the cam 2, and a spring-loaded wedge which engages the guide plate 43. .

Abstract: 901,358. Slub catchers; thread guides and tensioners; waxing threads. MARSHALL, C. R. May 23, 1960 [May 29, 1959], No. 18043/60. Classes 120 (2) and 120 (3). In catching slubs &c., a thread is pulled through a restricted passageway ; when a slub occurs the thread is deflected out of the passageway into an open air-space and the slub is arrested and the thread severed. In the apparatus shown diagrammatically in Fig. 1, the thread is pulled through a slot A in an inclined deflector-member 45 between guides 37, 41; the slot is just wide enough to take the thread so that when a slub occurs the thread is deflected to pass through a second slot B in an entrapping-member 46 where the slub is arrested and the thread severed either by increased tension or by a knife. Lint &c. wiped from the thread at 45 is usually dispersed due to the inclination of the member and any collecting is carried on by the slub and falls between members 45 and 46. The path of the thread may be inclined at 10 degrees and the members respectively inclined at between 35-45 degrees and 25-35 degrees. The members need not be vertically arranged, but the lower part of 46 should be in a plane extending from the upper edge of member 45 to guide 41. The width of the slots may be adjustable and converging. In Fig. 6, members 45, 46 are carried by a support 20, each member consisting of two plates, one of which is adjustably mounted to vary the size and convergency of the slot. Member 45 is carried on an inclined part 60 of the support and one of its constituent plates is spring-urged towards the other ; member 46 is carried on a bracket 75 adjustable by screws 83, 84 in part 60.

[Classes 38 (i) and 41.] A cell, particularly for the decomposition of alkali-metal chlorides for the production of alkali and chlorine. comprises a base member supporting a number of vertically disposed anode plates and an annular shell supporting a number of vertically disposed cathode members which alternate with the anode members when the shell is superposed on the base. In the cell shown in Fig. 3, each anode comprises a set of three graphite blades 4 embedded in a lead slab 11 cast into a recess in the concrete base 2, notches 44 and holes 43 being provided for keying. Connection is made with the lead by a tinned copper bus-bar 12. The surface of the lead slab 11 is protected by layers 15, 16 of cement and bitumen respectively. The cathode comprises a sheet 5, Fig. 7, of perforated metal bent in U-form and covered with an asbestos diaphragm to form cathode chambers the outer ends of which communicate with a common passage 6 ; the chambers are supported by internal reinforcing members 47 secured to the peripheral angle-iron frame 3. The seams 10 at which the perforated metal is welded to the frame 3 are covered by a gasket 42 of putty or bitumen. The diaphragm material may be deposited on the cathode as described in Specification 381,190. As shown, the anode and cathode members are disposed in two parallel banks between which is a medial space serving as a return path for electrolyte rising between the electrodes. The cathode assembly frame is surmounted by an externally lagged concrete cover 1 provided with a gas exit 40 and thermometer 35. Hydrogen is withdrawn from the cathode chambers at 34. Machined joints are provided between the superimposed parts which are secured together by bolts 36. Brine before entering the cell is heated by passage through a pipe coil 31 surrounded by an outer pipe coil 28 through which the effluent alkali from the passage 6 is passed in the contrary direction before discharge. The pressure-head between the ends 26, 29 of the coil 28 is variable so as to control the rate of heat transfer. The coil 28 is mounted around the frame 3 in lagging retained by a cement layer 25. The electrolyte may be introduced through the cover 1 as a downward jet in such a direction as to set up circulation, and disposed at such a height above the anolyte that the jet is broken and electric connection to the liquid in the coil 31 avoided. Electric connection between two cells is made by copper laminations riveted and sweated to the cathode frame 3 which are interleaved with and clamped to laminations secured to the bus-bar 12 of the next cell. The cell is supported on insulators 45.
